Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 19
His disciples say unto him, If the case of the man be so with his wife, it is not good to marry. But he said unto them, All men cannot receive this saying, save they to whom it is given. For there are some eunuchs, which were so born from their mother’s womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven’s sake. He that is able to receive it, let him receive it.
For they are born such, just as others are born having six or four fingers. For if God according as He formed our bodies in the beginning, had continued the same order unchangeably, the working of God would have been brought into oblivion among men. The order of nature is therefore changed at times from its nature, that God the framer of nature may be had in remembrance.
